Juniper firewalls compromised by spy code: What you need to know

Juniper Networks is warning customers to patch their NetScreen enterprise firewalls against spyware that enables attackers to take over the machines and decrypt VPN traffic among corporate sites and with mobile employees.

The danger is that attackers could exploit the code “to gain administrative access to NetScreen devices and to decrypt VPN connections,” Juniper says in a security announcement.

It would enable smart attackers to exploit the vulnerability and wipe out log files, making compromises untraceable, the company says.
